Re: Banks migrate from mainframes to AI-driven cloud tech
How do containers in the cloud differ from containers on the mainframe? How difficult is it to provision a new z/VM virtual machine with contemporary software? ow much is just different coverage in the in-flight magazines versus substantive benefits of the cloud? -- Shmuel (Seymour J.)

Lets have a thought exercise: WAS Banks migrate from mainframes to AI-driven cloud tech
Who wants to have a thought exercise where we can see where we end up. In early wood frame constrution, joins were done with things like friction dovetails and Pegs. Along comes the next techology - metal.Look at the new thing - Nails. Lets use them to join our wood. Metal technology changes --- and we get Screws. An everybody rejoices at the wonderful new uses. Parallels are glue and its family But wait, how do we join metals --- oh yeah... metal pegs (rivets)... Pegs can still work, and look at this new Bolt thing. With parallels called welding. - NOW --- Everybody step back from your current comfort zone. Be it mainframe or server. On-siteor Cloud. And we want to 'DO' something using computers. What I believe is that any technology can be beaten into shape to perform the task with enough effort and time. The problems start when humans get involved. ALL humans have a bias to use what they find easiest and know best. Put two or more groups of these to the task and you will get many many designs... all of them using the tools the designer knows best. Then you have to "pick a winner" and go with that.The decision may be based on categories totally outside the technology arguements (like budgets or legal requirements or the manager going out to lunch with a sales rep). Time passes and new technologies come along... New thoughts on how to accoimplish the task... With everyone arguing that "My" way is the best for an entire list of reasons that "I" view as important. The wars start when what "I" think is important is not what "You" think is important. This can degrade into personal attacks and calling the competitor degrading names. - Now for the thought exercise: IF we apply this view to all of the newsgroups, web articles, sales materials and water cooler chats.Can you find reasons why Tasks don't get done and are always being redone? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: XTL64E_EXTENTADDR
It should be apparent that if you're using a 4-byte address from an 8-byte PSW, you cannot possibly handle information from an extent list that might have addresses above 2G. 16-byte PSW with its 8-byte address (and similarly GR high halves) is provided only for time of error. That's not either SDWAEC1/SDWAEC2 of course. If using 8-byte PSW, XTL64 is not needed, the "normal" extent list will do. Further, I don't recall how you are actually thinking to locate the XTL64. If you're using CSVQUERY (such as based on the address that you seem to be interested in), I can say only that that is a bad thing to do in a "general recovery routine" for all the reasons I laid out long ago to one of your earlier posts, including making sure that your recovery routine actually gets the opportunity to do the things that recovery routines must do (and not get short-circuited by calling an unnecessary routine that (just because of the nature of things) might unexpectedly fail). You might survive if you have established nested recovery to catch such a failure (which would surely be the minimum you have to do). But if you do provide CSVQUERY with an address and it finds it (based on such things as your search criteria - JPALPA or just JPA, for example), then you have a change to get an XTL64.
